The basilar artery is the only large artery in which two flows merge, and this is reflected in the flow downstream. We report quantitative flow-velocity measurements with a phase-based MR technique, i.e. the Fourier velocity encoding method, in the basilar artery of a volunteer. To our knowledge, this has not previously been performed successfully. A comparison is made with the results of flow velocity measurements in the basilar artery with transcranial Doppler ultrasonography; the techniques agreed very well. Although Doppler ultrasonography is still most widely used, no information on the flow rate and the flow velocity distribution in the basilar artery can be provided. MR flow measurement techniques appear promising when detailed information on the flow velocity distribution and flow rate is needed.
基底动脉是唯一一条有两股血流汇入的大动脉，这一点在下游血流中有所体现。我们报告了采用基于相位的磁共振技术，即傅里叶速度编码方法，对一名志愿者的基底动脉进行血流速度定量测量的情况。据我们所知，此前尚未成功进行过此类测量。将其与经颅多普勒超声测量基底动脉血流速度的结果进行了比较；两种技术的结果非常吻合。尽管多普勒超声仍然应用最为广泛，但无法提供基底动脉的血流量和血流速度分布信息。当需要关于血流速度分布和血流量的详细信息时，磁共振血流测量技术似乎很有前景。
